IINTTED uSTATES PATENT mOmtrent WILLIAM J. SUMNER, OF HOLYOKE, MASSACHUSETTS, ASSIGNOR TO THE COBURN TROLLEY TRACK MANUFACTURING COMPANY, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 537,395, dated April 9, 1895.

Application filed May3'1894t Serial No. 509'934. (No model.)

To all whom t may concern.-

Beit known that I, WILLIAM J. SUMNER, a citizen of the United States, residing at Holyoke, in the county of Hampden and State of Massachusetts,have invented new and useful Improvements in Trolley- Supported Door- Hangers, of which the following is a s pecitication.

This invention relates to trolley supports for doors, which doors are usually arranged to slide longitudinally along, or within, a partition, or other wall.

The object of the inventionis to generally improve the construction of the trolleys, or roller carriers, and the invention consists in constructions and combinations of parts all substantially as will be hereinafter particularly described.

In the drawings forming part of this specification,-Figure 1 is a Vertical cross sectional view showing the overhead trolley-track, trolley, and an upper portion of the door supported by the trolley. Fig. 2 is a central longitudinal section of the same. Fig. 3 is a horizontal longitudinal section of the body of one of the trolleys, or roller carriers. Fig. 4 is a vertical cross sectional view of one of the carriers. Fig. 5 is a perspective view of an externally shouldered sleeve which enters into the construction of the body of the trolley.

In the drawings, A represents a portion of the trolley track which is of a now well known construction.

B represents one ot the trolleys, or roller carriers, of which two are usually employed for and above each door. Each carriage, here shown, comprises the body, a, trucks, or rollers, b, and the pendant, d. Each body consists of fiat, opposing, rectangular plates, 10, 10, which have through them, at points toward their ends, the round holes, 12; the separating sleeves, 13, 13, and the shouldered rivets, 14, 14, which are set between the plates with their ends extending outwardly through perforations in the plates, while against the outer faces of the plates the rivets are upset. The sleeves, 13, which near their ends are externally shouldered, as seen at 16 5 Figs. 3, 4, and 5, are by said rivet-united plates held with their reduced extremitiesin place within said holes, 12, to constitute the bushings for the roller bearings, f, for the axles of the trolley wheels. Now it will be perceived that the axles, b2, of the trolley wheels are passed centrally through said bushings, said axles being l surrounded by the rollers, f, and that said axles have suitably within their ends the shoulders, b3, (see Fig. 4) while upon the attenuated ends and against said shoulders the rollers are driven. It will also be perceived that the inner faces of the rollers, b, b, serve to retain the anti-friction rollers, f, against endwise displacement. The pendant, d, consists of a bar which is dat and perforated at its upper portion and round and screw-threaded at its lower extremity. The at upper portion is passed within and-between the plates, 10, 10, of the trolley carriage body and held by the cross-pin, 1S, which latteris retained by the spring-key, 19. The pendant may, of course, freely move along through the slot of the trolley track.

`The adjustable connection between each pendant and the upper portion of the door is made as followsz-Within the` top edge of' the door G is the recess, g, while overlying such recessed edge is the plate, h, which is secured by the screws, 20, and which has the round hole, 22. The round, screw-threaded lower extremity of the pendant is passed concentrically within the hole of the plate, while the externally shouldered nut, j, screw engages the extremity of the pendant, its flange, or shoulder, 23, lying within said recess of the door,pwhile its cylindrical body projects upwardly through the hole, 22, win theplate, and above the upper face ot' the plate, where it is provided with the spanner holes, 24, or equivalent means, to facilitate the turning of the nut to eect the adjustment.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The carriage, to run on a trolley track, which consists of the body composed of parallel opposing plates with the holes, 12, 12, the shouldered sleeves, 13, and the rivets for uniting the plates, and the axle-united rollers, b, b, the axles of which are passed-through the sleeves, and have the surrounding rollers, f, which are held against endwise dis-v placement from within the sleeves by the iuner sides of the rollers, b,substantially as described.

2. The combination with the carriage body comprising the opposing plates and transverse 5 intermediate sleeves, of the axles passed through the sleeves, the anti-friction rollers surrounding the axles and rolling Within said sleeves, and the rollers, b, b, set on the ends of the axles outside of the plates and by their inner sides confining the anti-friction rollers ro against endwise displacement, substantially as described.
